EUCALYPTUS FLORA. 363 
lata, nervis lateralibus parallelis ante marginem connexis.” 
(Link’s ‘‘ Enumeratio,” p. 31.) 
Sweet’s reference is very brief :— 
“56. hypericifolia, (White), N.S.W., 1804. Greenhouse- 
shrub.” (Sweet. Hort. Brit. Ed. 2, p. 209.) 
I submit the following diagram as exhibiting the re- 
lations of #. amygdalina and FL. Risdoni, as far as we know 
them at present. But I repeat that much field work still 
requires to be done in regard to aberrant forms.

Var. alpina _— Var. elata 
BE .—EZ. linearis, Dehnh. 
Following is the original description, obtained from 
Kew. It has not been previously published in Australia, 
so far as I know. It is from Catalogus plantarum horti 
Camuldensis, Ed. ii. 1832, p. 20:— 
“ Bucalyptus linearis, Dehnh.—K. ramosissima. Ramulis 
viminalibus teretibusque levibus; foliis alternis linearibus 
subfalcatis subcrenulatis rugosiusculis in petiolo decur- 
rentibus apice uncinatis; cortice laevi punctato. Ramulis 
debilibus paniculatis. Folia uncias 3-4 longa, lineam 1 
lata. Species haec differt ab illis quae descriptae sunt in 
Catalogo MHorti Parisiensis; phrases quibus utitur cl. 
Desfontaines ejus Catalogi Auctor hic transcribo. Huca- 
lyptus rubricaulis. Ramis asperis; ramulis filiformibus : 
folus alternis, angusto-lanceolatis acutis petiolatis. 
“ Folia-uncias 2-3 longa, lineas 3 lata. 
“ Hucalyptus pulchella. Ramulis filiformibus; folis- 
alternis lineari-subulatis. 
“ Ramulis filiformibus paniculatis. Folia uncias 2 longa, 
lineam 1 late.” 
The original descriptions of #. rubricaulis, Desf., and 
£. wpulchella, Desf., have been inserted for  con- 
venience of reference. It will be observed that all three 
species have been described from leaf only. | Walpers 
(Rep. Bot. Syst. i1. 164), gives the following :-— 
“#. linearis, Dehnhardt (Rivista Napolitana, 1-3, p. 173).—
